REFRIGERATION Filed March 12, 1927 CHAIQLES C. SPQEEN [J2 UE'JZ 201* Patented Nov. 1 8, 1930 UNITED STATES PATENT OFFICE CHARLES C. SPREEIN, OF DETROIT, MICHIGAN, ASSIGNOR TO KELVINATOR CORPORA- TION, OF DETROIT, MICHIGAN,'A CORPORATION OF MICHIGAN REFRIGERATION Application filed. March 12, 1927. Serial N0. 174,883.

My invention relates to refrigeration, and particularly to compressing and condensing apparatus for domestic mechanical refrigerating units, and the principal object of my in 5 ventionis to providenew and improved apparatus of this type. In the drawings accompanying this specification and forming a part of this application I have shown, for purposes of illustration, one form which my invention may assume, and in these draw- H Iigure 1 is a side elevationof the embodiment of my invention disclosed herein, while Figure 2 is an end elevation of this embodiment of my invention.

The embodiment of my invention illustrated herein comprises: a compressor 11 having an inlet 12 adapted to receive a duct 13 leading from theoutlet of refrigerant expansion apparatus not shown, provided with an operatingtshaft 14 carrying an operating pulley 15, and provided also with an elon-v gated bearing 16 supporting the emerging end of the operating shaft 1 1 and containing a suitable seal for preventing escape of refrigerant betwen the shaft 14; and the bearing 16; a motor 17 provided with an operating shaft 18 carrying a pulley 19 connected by means of a belt 20 to the compressor pulley 15, and

supported upon a common base 21 serving also to support the compressor 11; and a con denser 22 mounted upon the common base 21,-

comprising a pair of drums 23 carrying fins 24: to increase the heat radiating capacity 3 thereof, each having its upper end connected by means of a duct 25 to the outlet 26 of the compressor 11 and its lower end connected by means of a duct 27 to a T 28 adapted to receive a duct 29 leading to the inlet of the re- 49 frigerant expansion apparatus, and disposed on oppositesides of the, compressor operating shaft bearing 16 between the compressor 11 and the compressor flywheel 15.

In the embodiment of my invention herein shown the compressor pulley 15 is formed with a relatively heavy rim 33 acting as a flywheel arranged to equalize the power requirement of the compressor 11 over its operating cycle, and in addition has its interior formed as a fan 34=comprising a hub 35 acting as the hub of the compressor pulley 15, and blades 36 acting as spokes supporting the rim 33 from the hub 35,-the'fan 34, upon operation of the compressor 11, and because of the location of the parts, being obviously effective to force a current of air over the condenser 22 and compressor 11 to assist in conveying heat from the condenser 22 and in maintaining cool the compressor 11. I

Fromthe above description it will be'obvious to those skilled in the art that I have provided compressor and condenser apparatus requiring a smaller over-all space While still permitting the use of a single fan mounted on the compressor shaft for cooling both the condenser and the compressor. At thesame time it will also be obvious to those skilledin the art that the particular embodi ment of my invention herein shownand described embodies advantages other than those specifically pointed out herein, and also that the embodiment of my invention herein shown 'may be variously changed and modlfied without departing from the spirit of my invention or sacrificing the advantages thereof, particularly that the condenser may be built in a variety of-otherv forms and shapes, that even with a cylinder condenser the cylinders may be arranged in other ways than those herein shown, and that the fins for facilitating radiation from the condenser may be dispersed with if desired, or may be replaced by other means for the same purpose.

Under these circumstances it will be obvious to those skilled in the art that theembodiment of my invention herein shown is illustrative only, and that my invention is not limited thereto.

I claim:

A condenser for refrigerating apparatus comprising apair of closed spaced cylinders, said cylinders extending in parallel relation in a Vertical plane, spaced circular fins extending in a horizontal plane from said cylinders, a common inlet connection for said cylinders, a common outlet connection for said cylinders, a common horizontally disposed support for said cylinders, and means for securing the bottom portions of the latter rigidly to the support.

In testimony whereof hereunto afiix my signature.
